Answer:
Alternate Interior Angles
Step-by-step explanation:
Angles can be corresponding; alternate or same side; or interior or exterior. The angles 2 and 8 are on opposite sides of the transversal; this means that they must be alternate angles. Additionally, they are both within the parallel lines, so they are interior. Alternate interior angles are always congruent. Therefore, their measurements must be equal.

Answer:
can be expressed in nested form as 
Step-by-step explanation:
Considering the polynomial

Expressing the polynomial by nesting
So,

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

Step 3) Repeating the previous step until all terms are within the equation.
So,

Therefore,
can be expressed in nested form as
